Calcule le quotient (le résultat de l'expression x/y) et le reste (le résultat de l'expression x%y) simultanément. (depuis C++11)

Calcule le quotient et le reste en même temps. Le quotient est le quotient algébrique avec une partie fractionnaire mis au rebut (tronquée vers zéro). Le reste est telle que quot * y + rem == x. (avant C++11)

Original:

Computes quotient and remainder simultaneously. The quotient is the algebraic quotient with any fractional part discarded (truncated towards zero). The remainder is such that quot * y + rem == x. (avant C++11)

Notes

Jusqu'à ce que C + +11, la direction d'approximation du quotient et le signe du reste dans le haut-opérateurs de division et le reste a été définie par l'implémentation si l'une des opérandes est négatif, mais il était bien définie dans std::div .

Original:

Until C++11, the rounding direction of the quotient and the sign of the remainder in the built-in division and remainder operators was implementation-defined if either of the operands was negative, but it was well-defined in std::div.
